Final answer:
The correct screw spacing for 1/2" drywall on studs that are 16" on center is 12" on center.
Step-by-step explanation:
The spacing for screws for 1/2" drywall when the wall studs are 16" on center and no adhesive is used is typically 12" on center.
This ensures that the drywall is securely fastened to the studs and can support its own weight as well as additional loads from items like pictures, shelving, or mounted televisions. When placing screws into the drywall, it's essential to ensure that the screws go into the center of the studs to provide maximum holding strength.
The distance between the vertical studs is 40.64 centimeters.
To convert inches to centimeters, we use the conversion factor 2.54 centimeters per inch. Multiplying 16 inches by 2.54 centimeters per inch gives us a distance of 40.64 centimeters.
